Abstract
A coiled reinforced retractable sleeve that provides a stent delivery system with improved longitudinal stiffness, lateral flexibility and overall pushability while maintaining dimensional stability. The coil reinforced retractable sleeve includes a spiral wound ribbon encapsulated between an inner and an outer laminate which form an elongated tubular body adapted to slidably receive an intravascular catheter. The tubular body has a first end adapted to connect with a manipulating device for effecting relative longitudinal movement of the intravascular catheter and sleeve and having a second end adapted for egress and ingress of the intravascular catheter.
